Schematic of nose-poke reward association task with activation of LHb input to the MRN (left) and examples of task performance (including timing of nose pokes, licks and completed (compl.) trials) of a control mouse and a mouse with activation of LHb input to the MRN. Light blue boxes indicate laser stimulation periods. Right, average number of completed trials during laser stimulation in tdTomato mice and mice with activation of LHb input in the MRN ( n = 14 and 10 mice, respectively).
